"If you had to pick one set of Elizabeth's CDs to buy, the Knees and Ankles #1 set is the one. These 30 minute lessons target all the movements you need to have in your movement tool box for easy standing and walking. I love Elizabeth's soothing, clear voice--and her instructions are easy to follow. After doing these lessons the comfort in my legs greatly improved my walking and standing. I can stand for longer lengths of time and have more stamina. My aches and pains are gone. I recommend this series to anyone who wants to stand and walk with ease. I find myself returning to them whenever I need a gentle reminder of how I can make things even easier."
